Function shli::input::read_commandline

pub fn read_commandline(
    stdin: StdinLock, 
    stdout: &mut Stdout, 
    completion: impl Fn(&str) -> Vec<String>
) -> Result<Vec<String>>

Prompt for a single command line.

This function reads and returns a command line, after prompting with > . Line editing with backspace and ALT+backspace is supported.

If TAB is pressed by the user, the callback function completion is asked for possible argument completion. If it returns exactly 1 completion, it is used, if it returns more, they are displayed.

If Ctrl+C is pressed, this function returns Err(Error::new(ErrorKind::Other, "Ctrl-C pressed."), while an EOF of stdin or Ctrl+D will return the error type ErrorKind::UnexpectedEof.

On success, read_commandline returns a Vector of command line components (command + arguments).

For example, the following input:

> print out "example command"

will return vec!["print", "out", "example command"].
